Electric Motor & Generator Simulations Software

Electrical machines are electromechanical energy converters where electric motors convert electromagnetic energy to mechanical energy while electric generators convert mechanical power to electricity.  They play a crucial role in our everyday life whether at home, in the car, in the train, in the bus, in the office, or at the factory.  They produce and consume most of the world’s energy. They come in all kind of shape and form such as brushless, with brushes, DC, AC, switched reluctance, induction, permanent magnet, synchronous, asynchronous, translational, rotational, variable speed,  claw pole, very small, series, shunt, universal, very large, and multi-phases.

Challenges for Electrical Machine Designers 

Electrical machines have been around since 1832 when William Sturgeon invented the first DC motor.  Yet, it is becoming increasingly challenging to design and manufacture them due to various factors, including:

  • How to achieve a high power density to meet the ever decreasing size and weight.
  • How to achieve a high efficiency over a wide torque and speed ranges.
  • How to minimize operational failure or fault.
  • How to meet the ever increasing harsh operation conditions and natural environment.
  • How to meet the increasing Government Legislations to improve design efficiencies while remaining competitive. 
  • How to minimize the cost in a very competitive industry.

To meet the above challenges, electrical machine designers have increasingly been utilizing electrical machine simulation software and CAD packages.  However, most packages fall short of adequately simulating real-life problems because electrical machines entail moving parts and components which complicate the simulation process since they necessitate the coupling of electromagnetic field equations to the mechanical motion and kinematic equations.  EMS makes the exception as it is seamlessly integrated not only in Solidworks and Autodesk Inventor but also in Solidworks Motion.

Powered by Solidworks Motion 

EMS is powered by  Solidworks Motion, the most versatile and powerful mechanical motion package.  Whether your electrical machine involves 1 DOF motion or all six DOF, EMS can handle your design.  The coupling of EMS to Solidworks Motion is hassle-free.  After creating a Solidworks Motion study, simply instruct EMS to couple to it.  The following examples demonstrate to you the power of EMS and Solidworks Motion
